Years 5 and 6 combined this morning to practice using protractors together. Mrs Powell made a complicated-looking sheet for us to measure but we quickly spotted that we didn’t actually need to measure every single angle. As long as we knew that a straight line had 180 degrees, we could save ourselves lots of time. We then checked our measurements to ensure they made sense. We could do this as we know that the sum of the internal angles for a triangle is 180 degrees, 360 for a quadrilateral, and 540 for a pentagon.
